The production process comprises a step (A) in which an alkali-treated tobacco source is heated to make the tobacco source release a flavoring ingredient into a gas phase, a step (B) in which the flavoring ingredient released into the gas phase is brought into contact with a given solvent which is a liquid substance at ordinary temperature, thereby trapping the flavoring ingredient in the given solvent, and a step (C) in which the given solvent is added to a constituent element.

A method for preparing a wetted vaping product for use with a vaping device includes providing dried leaf matter having been dried to remove moisture content therefrom; one of wetting, soaking, and immersing the dried leaf matter in a solvent; rehydrating the leaf matter with the solvent to increase overall weight of the dried leaf matter at least 5% to 10%; and sizing the leaf matter before and/or after the act of wetting, soaking, and immersing to fit within the vaping device. Another method includes providing leaf matter containing plant oil; mixing the leaf matter and a liquid solvent by immersing and/or soaking the leaf matter with the liquid solvent in a sterile container for at least 30 days; extracting liquid from the mixture of leaf matter and the liquid solvent; and filtering the separated liquid to remove the leaf matter of 3.5 microns to larger from the separated liquid.

The present disclosure provides a method for extracting tar aroma components from a cigarette butt and use of the tar aroma components in a cigarette. The method includes the following steps: (1) adding the cigarette butt to an extraction solvent, and carrying out ultrasound-assisted extraction to obtain an extraction solution; (2) centrifuging the extraction solution, and carrying out vacuum distillation on the supernatant to obtain a concentrated extractum; and (3) carrying out molecular distillation on the concentrated extractum, and collecting a light fraction of the molecular distillation to obtain the tar aroma components. In the present disclosure, the cigarette butt is used as a raw material, through the ultrasound-assisted extraction and separation by the molecular distillation to extract the tar, harmful substances in the tar are removed, and the aroma components are retained. The tar aroma components are applied to a heat-not-burn cigarette, so that the aroma, smoke and taste characteristics of the heat-not-burn cigarette are improved, and the problems of insipidness and uneven aroma release of the heat-not-burn cigarette are solved effectively.

A liquid tobacco composition comprises tobacco dissolved in an ionic liquid. Removal of selected tobacco constituents is aided by dissolving the tobacco in the ionic liquid. The tobacco, having selected constituents removed, may be regenerated from the liquid tobacco composition by separating the tobacco from the ionic liquid.

An oil-infused plant product and method of infusing is provided. The method includes placing dried botanical matter with an alcohol and oil mixture into a pressurizable container, pressurizing and heating the pressurizable container, allowing the botanical matter and oil/alcohol mixture to remain in the container for a development time period while the oil is drawn into the botanical matter, and removing the oil/alcohol mixture via a vacuum. The botanical matter may be a processed plant matter, such as a blunt wrapper, or may be a natural or minimally processed plant matter, such as dried edible plants, smokable herbs, or herbs suitable for brewing (such as tea, coffee, and herbal tea components). The oil may be any nontoxic oil.

Provided is an aerosol generating apparatus, including: a supercritical extraction unit that includes at least one of tobacco and aromatic plant as a raw material, and extracts an extraction component from the raw material by a supercritical fluid; a collection unit that collects the extraction component discharged from the supercritical extraction unit as a collection material; an inlet part that is disposed between the supercritical extraction unit and the collection unit and serves as a path through which the extraction component is introduced from the supercritical extraction unit into the collection unit; a heating unit that heats at least one of the supercritical extraction unit and the collection unit, and a body part in which the supercritical extraction unit, the collection unit, the inlet part, and the heating unit are disposed.

A method of manufacturing a flavor source includes: a step A of adding a basic substance to a tobacco raw material; a step B of heating the tobacco raw material added with the basic substance and releasing an inhaling flavor component into a vapor phase from the tobacco raw material; a step C of collecting the inhaling flavor component released into the vapor phase in the step B; a step D of washing a tobacco residue being the tobacco raw material obtained after the inhaling flavor component is released in the step B, with a washing solvent; a step E of pulverizing or cutting the tobacco residue obtained after being washed in the step D; and a step F of adding the inhaling flavor component collected in the step C to the tobacco residue obtained after pulverized or cut in the step E.
